Astigmatism is a common vision condition that affects millions of people worldwide. It occurs when the cornea or lens of the eye is irregularly shaped, causing blurred or distorted vision at all distances. If you’re one of the many individuals living with astigmatism, you may be wondering how to fix it. In this article, we’ll delve into the world of astigmatism correction, exploring the various treatment options available and what you can expect from each.
Understanding Astigmatism
Before we dive into the correction methods, it’s essential to understand what astigmatism is and how it affects the eye. Astigmatism occurs when the cornea or lens of the eye is shaped more like a football than a sphere. This irregular shape prevents light from focusing correctly on the retina, resulting in blurred or distorted vision.
There are two types of astigmatism:
- Corneal astigmatism: This is the most common type, where the cornea is irregularly shaped.
- Lenticular astigmatism: This type occurs when the lens inside the eye is irregularly shaped.
Symptoms Of Astigmatism
The symptoms of astigmatism can vary from person to person, but common complaints include:
- Blurred or distorted vision at all distances
- Eye strain or fatigue
- Headaches
- Difficulty driving at night
- Squinting to see clearly
Treatment Options For Astigmatism
Fortunately, there are several treatment options available to correct astigmatism. The best course of treatment for you will depend on the severity of your astigmatism, your age, and your personal preferences.
Glasses And Contact Lenses
Glasses and contact lenses are the most common treatment options for astigmatism. Both can be used to correct nearsightedness, farsightedness, and astigmatism.
- Glasses: Glasses can be prescribed to correct astigmatism. The lenses will be shaped to compensate for the irregular shape of the cornea or lens.
- Contact Lenses: Contact lenses can also be used to correct astigmatism. There are two types of contact lenses available: soft contact lenses and rigid gas permeable (RGP) lenses. Soft contact lenses are more comfortable to wear, while RGP lenses provide sharper vision.
Refractive Surgery
Refractive surgery is a popular treatment option for astigmatism. There are several types of refractive surgery available, including:
- LASIK (Laser-Assisted In Situ Keratomileusis): LASIK is a popular surgical procedure that uses a laser to reshape the cornea.
- PRK (Photorefractive Keratectomy): PRK is a surgical procedure that uses a laser to reshape the cornea.
- LASEK (Laser-Assisted Subepithelial Keratomileusis): LASEK is a surgical procedure that uses a laser to reshape the cornea.
Implantable Lenses
Implantable lenses are another treatment option for astigmatism. These lenses are surgically implanted inside the eye to correct vision.
- Toric Lenses: Toric lenses are designed to correct astigmatism. They are shaped to compensate for the irregular shape of the cornea or lens.
- Multifocal Lenses: Multifocal lenses are designed to correct nearsightedness, farsightedness, and astigmatism. They allow for clear vision at all distances.
Corneal Reshaping
Corneal reshaping is a non-surgical treatment option for astigmatism. It involves wearing a specialized contact lens at night to reshape the cornea.
- Orthokeratology (OK): OK is a non-surgical procedure that uses a specialized contact lens to reshape the cornea.
- Corneal Reshaping Therapy: Corneal reshaping therapy is a non-surgical procedure that uses a specialized contact lens to reshape the cornea.
What To Expect From Astigmatism Correction

What Is Astigmatism And How Does It Affect Vision?
Astigmatism is a common vision condition caused by an irregularly shaped cornea or lens inside the eye. This irregular shape prevents light from focusing properly on the retina, resulting in blurred or distorted vision at all distances. People with astigmatism may experience eye strain, headaches, or difficulty driving at night due to the glare from oncoming headlights.
In addition to blurred vision, astigmatism can also cause eye fatigue, squinting, and difficulty seeing fine details. The condition can occur alone or in combination with other vision problems, such as nearsightedness or farsightedness. Astigmatism can be diagnosed during a comprehensive eye exam, and there are several treatment options available to correct the condition and improve vision.
What Are The Causes And Risk Factors Of Astigmatism?
Astigmatism is often caused by an irregularly shaped cornea or lens inside the eye. The cornea is the clear dome-shaped surface at the front of the eye, and the lens is a clear structure behind the iris that changes shape to focus light on the retina. In people with astigmatism, the cornea or lens is shaped more like a football than a sphere, which prevents light from focusing properly on the retina.
Several factors can increase the risk of developing astigmatism, including genetics, eye injuries, and certain medical conditions, such as keratoconus. People who have a family history of astigmatism are more likely to develop the condition, and eye injuries or surgeries can also cause astigmatism. Additionally, certain medical conditions, such as keratoconus, can cause the cornea to thin and become irregularly shaped, leading to astigmatism.
How Is Astigmatism Diagnosed And What Are The Symptoms?
Astigmatism is typically diagnosed during a comprehensive eye exam, which includes a visual acuity test, a keratometry test, and a refraction test. The visual acuity test measures the sharpness of vision, the keratometry test measures the curvature of the cornea, and the refraction test determines the correct lens prescription to correct vision problems.
The symptoms of astigmatism can vary depending on the severity of the condition, but common symptoms include blurred or distorted vision at all distances, eye strain, headaches, and difficulty driving at night due to glare from oncoming headlights. People with astigmatism may also experience eye fatigue, squinting, and difficulty seeing fine details. In some cases, astigmatism can cause double vision or ghosting, which is a faint second image that appears alongside the main image.
What Are The Treatment Options For Astigmatism?
There are several treatment options available for astigmatism, including glasses, contact lenses, and refractive surgery. Glasses and contact lenses can correct astigmatism by refracting light properly onto the retina, and they are often the simplest and most cost-effective treatment options. Refractive surgery, such as LASIK or PRK, can also correct astigmatism by reshaping the cornea to improve the way it focuses light.
In addition to these treatment options, there are also several types of contact lenses that can correct astigmatism, including toric lenses and rigid gas permeable lenses. Toric lenses are designed to correct astigmatism and are available in soft and rigid gas permeable materials. Rigid gas permeable lenses can also correct astigmatism and are often used for people with high levels of astigmatism.
Can Astigmatism Be Corrected With LASIK Surgery?
Yes, astigmatism can be corrected with LASIK surgery. LASIK, or laser-assisted in situ keratomileusis, is a type of refractive surgery that uses a laser to reshape the cornea and improve the way it focuses light. During the procedure, the surgeon creates a thin flap in the cornea, which is gently lifted to expose the underlying tissue. The laser is then used to reshape the cornea, and the flap is replaced to heal naturally.
LASIK surgery can correct astigmatism by reshaping the cornea to improve the way it focuses light. The procedure is typically painless and takes about 30 minutes per eye. Most people can see an improvement in their vision within the first few days after surgery, and the full effects of the procedure can take several weeks to a few months to become apparent.
What Are The Risks And Complications Of Astigmatism Correction?
As with any medical procedure, there are risks and complications associated with astigmatism correction. The risks of glasses and contact lenses are relatively low, but they can cause eye irritation, dryness, and infection. Refractive surgery, such as LASIK, carries more significant risks, including dry eye, infection, and visual disturbances, such as halos or glare.
In rare cases, refractive surgery can also cause more serious complications, such as undercorrection or overcorrection, which can require additional surgery to correct. Additionally, some people may experience a condition called dry eye, which can cause eye irritation and dryness. It is essential to discuss the risks and complications of astigmatism correction with an eye doctor to determine the best treatment option for your individual needs.
Can Astigmatism Be Prevented Or Reduced?
There is no surefire way to prevent astigmatism, but there are several steps you can take to reduce your risk of developing the condition. Maintaining a healthy lifestyle, including a balanced diet and regular exercise, can help keep your eyes healthy. Wearing protective eyewear, such as goggles or sunglasses, can also help prevent eye injuries that can cause astigmatism.
In addition to these steps, regular eye exams can help detect astigmatism and other vision problems early on, when they are easier to treat. If you have a family history of astigmatism, it is essential to schedule regular eye exams to monitor your eye health and catch any potential problems early. By taking these steps, you can reduce your risk of developing astigmatism and maintain healthy vision for years to come.
